TU ALL WHOM IT MAY CONCER'N: I

Bo it known that I, RICHARD C. M. Lox'nnL, of Covingion, in the county Kenton, cm State of Kentucky, have i-n'vonieci a. new and improved Mining, Tu'nnciling, and StOZICrDI'OSSiRg Machine; and 1 'io hereby decimc time following to be a i'uii, clear, one; exzict description of the nalure, consirnction, and opcrati0n'of the sonic,

v A track for the traversing plnii'orm is iniii down parallel with the upright fcii of the coal, &c. The forward n iij ustmcnt oi the machine on ii ;s platform is made after each traversing cot. chisels are operated alien ,noteiy by their respective engines, the iemling chisel cutting half the depth c-mi thc following one completing 'ihc cot, being reversed, and changed in cutting back. The motor is cichoc sitcom or compressed oi:- conducted to the engine by pipes from the exterior of the shaft or drift. Momentum is given to the strokoof the chisois bilondingfihe and the return motion is giiz'cn to the piston by thc-sfiecti-vc stroiw of the when piston, to it is connected by c working-beam. The steam is chn-uged,,as'the piston. passes a certain point in the cyiiniier, by the admission of the iivc steam to an auxiliary cylinder, whose piston works the valve. The motion of" .the-woricin g-beam which connecis the encis of the pitmon cctuntes a rock-shcft, ratchet, and ,shaft whose pinion "gears into the rock on fihflti'iuljsfi truck, The some shz ft has in thncad, with which a'cifitchmnt of the ti-Moose plofii'orm' is mmie to engage for the forward anc beckwcrli motions of the machine, egrpniii on ihe hitter engaging with c incl: on the pizstform to keep the mcchine in position.

In the drawings, A. il fs'cio the tracks, and A. c. central rack-har, which are laid down paraliai wiigh the uprighz of theicoai, stone, or other matcricl, which is being qunrrieti, or the stone which is beingihessed. This is intended "to-be laid in ccctions, collectively as iong as the length oi x ziz e'brcosi; of coal which is being mined, not? the machine works autcmzi'ticniiy fi om one end -to the other of this track, being reverscd by hand, and returning after reaching the inziicatiedi distance. Fig. 3 represents another arrangement of'the track, which is cnwcgi. In this case the track B E mini rock-he: ,Bi'crenrcs of ciroies, whose centre is the pivotni. point 3 of itiio fm'v'erse pint form D. J This ior n is speoioily intended for driving into the bank, making is drift or hcci in the accompanying diawings, forming opart of this specification, nnd in'whichgallery. Fi n 4; shows this leftist arrangement in seciicn, the traverse piatfo rm'n being. connectcciby the hm-s d to the pintie {L and having on its upper edgc i rzacioimt d, by which the machine is held in -position by the pawl ai cnd latch d"'",'cs shown in the eicvai-i in, E5. Those portions are iifted'ont of engcgemeniwhen the engine is be moved forward or back, that is, to o2 from the fcc oi the worii on its platform, which motion. is cfiected; "by merino to be described. I have spoken of the trcv'ersc track A A A or B B B, which fiifi'er in rcspcctofi the cur e of the io'tt'er, enri have also referred to the iravcrsc platform D, which 511m t c:- txcck on which it 'ie picced. In the former the motion of the platform is rectiiinecr, out in the latter it is in n'curyc. In each it is reciprocating by the engagement of the'spur-wheei E on om shaft e underneath the carriage E of the machine with the rock-bar A or B, cs ihc case may be. The construction and iarrangemcnt of the shaft e is perhaps better shown in fig. 6 than eiccwhere,'from Whic'ii'it wiii be seen that it has hearings of: e"- e at the respective ends of the carriage E. The cog-wheel E revolves with the shaft 0, but slips thereon, being secured by a spline to the shnit. I propose to describe the motions of the engines presently, bg'ics the :FEVGRBQ motion of the machine is automatic-and c'iepends npontiie motions of the pistons, I shall assume all!!! latter for: the present, and state that. the working-been F receives rotary, reciprocating, or vibratory motion therefrom. The edge of the working bean: F toward the engine has an extension beneath, to whichia socure' n yoke, d, which rocks the mm d", (see figs. 7 nndfifi one rotcfiaa the cog-ghee! oi, which is fastened to th shaft e. The romiion is psrformeil by tho-intervention of one or the other oi i112 pawl: a (2". Thromng-opo pow; into gear with the cog-wheel d rotates thoshnit e in one h'ecaion one; ,he other pow eontrqriwise, :aml Qlllri euaih'ol oi' the pawls is obtninegl by the penfiuions latch :3, whose motions inonoor the other direction raise the i espoctivo pools, or, as in fig. 8, by occupying n vertical position, hold thorn both out of engugemeni \i'ith the iiheol zuul permit the shafts to he znrned'hy the hnnii ci nnko' to shiis the machine on the .i'everse independently ofthomoiiyns ol' the engine. It is intended that ihe traverse. motion of the innohino shall he automatic, driving the ohi'sels into the breast of coal, for instance, to a given depth, mnlcing a. horizontal continuous fiesizre.

As soon on ii roaches-the oml oi the track, or sooner, if i'equirecl, the motion of the moohine he stopped. Theehisels are now chnngod and reversed ready for the remicn traverse, the necessity for and mode of doing whih will he presently explained. For the pnepose oi tnlaing another chip n forward-motion of izhe machine toward the bank is required, and this is eiiooteiihy raising the lever Good half net so as to engnge-with on thread 9' on tho ieh'oft c. The revolution of the shaft e by the hand-crook 5' wiil now give the xeqnired longihniinn-l niotion totho machine-om, or in, the new being toward the coal, and to aim right; enema say, for instance, two inches. The paw-ls a a are reversed so as to change ihe direction of orei'erse of the platform, angi the machine commences it s return motion the pool om} lawn cl ai keeping it in place, and the "not 5 being lowereri so the; the revolution of heehni'te, which isineoossnry'to rotate the irnveraing pinion E, Shnil not niieoe the longitudinal position oi' tire machine .ns ,ihe soreiv g revolves. Anohlique approach of the chisel to its work or recession irom' it may be attained by allowing the wheel E to mice simultaneously with the engagement of the thread 9'' with the clutch-nub g, the longitudinal and toeverso mofione being concurrent, and the gnotion being 'compound,.the resultant of the comhineci foicos. The eyiindei's H H are single-acting, and are operated by the p' 'osmnre of oomprosseii air oi oi sieohi eondncmo into the mine by pipes end immediately connected to the induction oi the vnlve-chnmho? oi the engine by a itloxihlo pipe. In enoh oyiinder is o piston-rod, I, loaded or weighted by n piston-block, 2', non passing through atnfiing-hoz at each end oi the cylinder. Each piston is provided at one eml with n ohisel, onri oi; the other end with a oross-heoii which moves; in or on slides,- the pimen 3 connecting the nespective pistons to the working-henna R-whioh hes been oineody inferred to as: moving the arm 03" The motions of the valve in the ohnmben ore mode by moons of the steam from the working eylindern oozing noon 3 piston in the smaller cylinder In 5; is e go'ekingflng of the oisiowhloek, end on the upper edge of the latter is a groove which oonimnnioetes niih the 5 m in 'ii'ii oylindei' oi the rem oihe pinion. the soon es-the piston passes the pooh m the livesienm in the oylimiez" posisee though the groove in the piston, through. 3902!; m, nml by ho sieom-pansnge 52o ihe omollew cylinder L, when: it nets ugnon one airleo-' the e'mnli piston and ootuntes the valve in chamber The eel-vein 'ohnmhei' nested. by in iron, Llho inn-mile i." of which ofi'orde moons; for monipnihiioe fio ohonge o? rename the steam M is zhe throtilewalve, which oomirols he orimioeion or eompr'ooseci. to the engine.- A9 the lower side of eeeh cylinder H H", onci nee? hum enci, in o 'gieniog, 1-3, which oclmito oil in anal from the cyiindei in from of the piston.

While Ido not confine. myself to any particular scale or proportions, I will indicatewhct I at present propose to use for o. given kind of work, and I do not Wish that my data should be taken as conclusive on the subject.- The machine represented in the drawings is intended for mining cool, the scale being one inch to the foot,

bolt. the cylinder approximately being occupied by the piston-block, whose weight gives effectiveness to the stroke "of thechieel. The lauded piston acts as a hammer, and the power of the stroke being greatly due to the weight of the iston the reaction of the blow is received thereon relievin the machiner of considerable 'ar and strain. p a g y .l
